One problem with crypto trading service is that of pumping that happens there but not to the hearing of all members. It is usually used for pumping and dumping and a big buyer may buy much but can't off load because price has gone off the the hook low
Don't fall into this trap, who provide pumping signals they are deep water fish, they advertise a coin and suddenly that coin pumped if you buy after hearing their signal you can't sell it to higher price even you can't sell it on your bought price, you will loss your money.
